We know that excessive drinking is a risk factor for atrial fibrillation (AF). AF is an abnormal heart rhythm characterized by the rapid and irregular beating of the atria (the two upper chambers of the heart). A new study published in the journal Heart Rhythm showed that even moderate drinking, approximately 2 drinks a day, can increase the risk for AF. Those who drank moderately showed evidence of electrical and structural changes in the heart which may be the reason for the increased risk of AF.
It is important to honestly discuss your usual drinking habits with your doctor because the amount of alcohol consumed is a modifiable risk factor for AF. Mild drinkers, 1 or fewer drinks a day, did not appear to be at increased risk for AF.
